What types of information can I share across my devices?

You can choose to sync the following types of information on your devices:

Tabs: your open tabs on other devices will be stored in the History menu on your computer, and in the Sync tab on your Android device.

Bookmarks: this allows you to access all your favorite sites on all your synchronized devices.

Passwords: this synchronizes your login information. This will be disabled if you use a master password
